Abstract
A drive circuit for supplying a drive current to a plurality of driven elements includes a plurality of drive output terminals to be connected to the driven elements. The drive output terminals are arranged with a specific pitch in between in an arrangement direction. The drive circuit further includes a plurality of drive transistors. Each of the drive transistors is arranged in an occupied area with a specific width in the arrangement direction larger than the specific pitch.

A drive circuit for supplying a drive current to a plurality of driven elements, comprising:
- a plurality of drive output terminals to be connected to the driven elements, said drive output terminals being arranged with a specific pitch in between in an arrangement direction;
- and
- a plurality of drive transistors, each of said drive transistors being arranged in an occupied area with a specific width in the arrangement direction larger than the specific pitch.
A drive circuit comprising:
- a plurality of drive output terminals to be connected to the driven elements, said drive output terminals being arranged with a specific pitch in between in an arrangement direction;
- and
- a plurality of drive transistors for supplying a drive current to a plurality of driven elements, each of said drive transistors being arranged in an occupied area with a specific width in the arrangement direction larger than the specific pitch, said drive transistors being formed in an L character shape and having a first gate length in a first direction and a second gate length in a second direction, said first gate length being different from the second gate length.
A drive circuit comprising:
- a drive transistor for supplying a drive current to a plurality of driven elements, said drive transistor including a gate electrode having a rectangular shape, a source region disposed along a first side and a second side of the rectangular shape, and a drain region disposed along a third side and a fourth side of the rectangular shape.
